Uuirsa starac PATENT' OFFICE CHARLESE. GREEN, oF sT. aUGUsTrNE, FLORIDA.

To all whom t mayl concern Be it known that I, CHARLES E. GREEN, a citizen' ofthe United States, residing at St. Augustine, in the'county of'St. Johns and State of Florida, have invented certain new and useful Improvements in'. Gil-Burners; and I do hereby declare the. following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.v

This1 invention relates to fuel burners and more particularly to an improved type Of oil burner.

It is an object of the present invention to provide an improved and simple type of burner readily adaptable for the combustion of light and heavy oils.

A further object ofthe invention isk to provide a construction of few and simple parts which can be readily assembled and Aeasily replaced when renewal is necessary.

A further object of the invention is to prov-ide a device of this kind which is shown organized and so constructed that the parts will have considerable, length of light and which can be adjusted and assembled' with ease by a personof average intelligence thus making thevdevice capable of use in an eX- tremely large field for the burning of various grades and kinds of oil.

Nlth the above and other objects in view as will be rendered manifest to those versed inthe art, therinvention consists of the construction, combination, and inl details and arrangements of the parts as more particularly described in the following specification' relative to the embodiment of the invention disclosed in the accompanying drawings, in which:

Figure 1 is a side elevation of the burner with a portion in vertical central section.

Fig. 2 is a transverse vertical section on the longitudinally medial plane.

Fig; 3 is a plan view of the burner partly broken away to show the air regulator.

Fig. 4 is a perspective view of the air regulator and Y Fig. 5 is a detailed sectional view of an adapter attachable to the oil nozzle.

vention the burner consists of an air chamber having upper and lower sections 2 and 3 having Vcomplementary intereengaging edges designed to make an approximately and sufficientlytight joint, both to keep the parts 1n proper register when assembled and to prevent the admission of air into` the chamber at the joint. The bottom section 3 is provided with a perforated bottom 5 and slidably arranged just below the bottem is a gate or regulator 6 perforated as at 7 to register with the perforations 8 in the bottom 5.V One end of the regulator 6 is provided with a suitable part 9 to be engaged by the user of the burner to enable it to be adjustable with respect to the apertures 8 so as to control the quantity of air admitted into the air chamber,

Oil to ber consumed in the burner may be supplied from any suitable source connections being made with the feed pipe 10 which extends upwardly lthrough the slot 11 in the regulator and through the support 12 on the bottom 5. The pipe is shown as provided with end or nozzle sections 13 which may be fastened or secured in place by any suitable means, as for instance, by a set screw 11i in the support or guide 12.

The upper end of the nozzle is shown as threaded as at 15, to receive a mixer or bafHe 16 which has a divergent surface and which is provided in its top with a pocket 17 to catch such oil as may overflow. The baflie 16 which is threaded upon the upper end of the said pipe is preferably adapted for catching the surplus oil, should the oil be fed through the pipe faster than the combustion takes place in the adapter. The mixer or member 16 is disposed within a downwardly convergent basin 18 to the lower and open end of which may be secured an air feeder 19 open at its lower end and provided with openings 20 through which air going into the chamber will pass upwardly and around the nozzle 13, thence passing through the annular space between the basin 18 and the baffle 16 over which it is directed into an upper extended combustion box 21 in the form of a cylinder suitably mounted upon the top section 2 and preferably attached thereto by suitable the size of the adapter through which the,

oil issues when admitted to the supply pipe 10 so that they maybe readily interchanged, according to the type of fuel being used. In Fig. 2,V the adapter tip is designated at 23 as threaded to theupper end of the nozzle and as rhaving a relatively large outlet 24: for the burning, for instance, of crude oil.

' In F ig. 5, the adapter tip 23 is provided with a relatively small aperture 24;, as for the burning of light oil.

When the oil is turned on and ignited in the tip 23, the deflector 25 which extends laterally across and above the box 21 is thrown to the siderupon its support 26. As soon as effective combustion starts', the defiector can again'be swung around into position over the outlet of the box 21.

From theabove, it will be seen that air to supply combustion is admitted through the perforated bottom 5 and controlled by the slidable regulator 6. The air passes upwardly into the basin 18, converges over the top Vof the baffle 16 and passes between the edge of the tip 23 and the bottoni of the box 21, so that fresh air is thoroughly intermixed with the gases produced by the combustion ofthe fuel and the state-of combustion is effectively active in the box 21,

said box being easily cleaned of carbon that* collects therein.

What I desire to claim is:

l. An oil burner comprising an air chamber having two sections, 'one forming the top and one forming the bottom, the lower section having a perforated bottom; an air regulator adjustably mounted on the bottom `to control the admission of air into the chamber through the perforated bottom; an oil feed pipe extending up into the chamber; a basin with an open bottom surrounding the upper end of the feed pipe; a baflie mounted on the upper end of the feed pipe and spaced-from the inner 'surface of the basin; and acombustion or fire box above the upper end of thev feed pipe; and an adapteradjustable to the discharge end of the feed pipe to adapt the burner to the combustion of a given grade of oil.
